The ruby has the privilege of its own name and up until the early 1800’s, it wasn’t known that both Rubies and Sapphires were made from the same mineral.

Sapphires are made from aluminum and can include many other small particles such as titanium and chromium. Even iron can be present in Sapphires. These elements help to make what is called color centers, or the part of the mineral that gives off beautiful colors. It should be noted that color centers are not fully understand, however, the color of a Sapphire can be changed usually by irradiation (with the help of extreme heat or other types of radiation).
